I, cleaning mould is arranged, into next group production.
Scheme three：A kind of dry solid sleeve insulator manufactures mould, and completing the cast of integral cannula insulator needs two sets
Various sizes of full skirt shape internal model cavity mould, two molds all have quiet mould 6, dynamic model 7 and lower mould 13（Because of the structure per mold
Form is identical with the mould structure form described in such scheme two, therefore does not illustrate）, its small-medium size full skirt mould use
Directly to pour into a mould interior insulation body 1, large scale full skirt mould forms one together with interior insulation body 1 has the set of full skirt shape thin-walled inner chamber
Bushing insulator mould, the full skirt insulator layer 2 for second pouring sleeve insulator.
Manufacture method using mold processing dry solid sleeve insulator is as follows, and it comprises the following steps：
A, according to the requirement of the epoxy resin of interior insulation body 1, by the small chi on the automatic gel pressure machine of epoxy resin
Very little interior cavity mould is preheated to suitable temperature；
B, mould is cleared up, by warmed-up sleeve insulator inserts annex, upper die head 11, lower die head 12 and screen layer 3 are installed
In mould specified location；
C, mould internal and external temperature is examined, when temperature is suitable, using suitable air pressure, the liquid ring that will be stirred in agitator tank
Oxygen tree fat batch mixing is expelled in the die cavity 8 of mould by the sprue 9 on mould and material feeding groove 10；
D, rule of thumb judge, confirm that epoxide resin material has filled in die cavity 8, pressurize of pressurizeing, continue material feeding, it is ensured that products-tree
Compact density after fat solidification；
E, confirm that product solidifies in in-mold molding, die sinking, take out shaped article；
F, removing surface is carried out to shaped article；
G, using cavity mould in large scale, by molded 1 surface roughening processing of interior insulation body, it is placed in cavity mould in large scale
It is interior, thin wall cavity is formed in interior insulation body 1 and large scale between cavity mould, then change mould material be outdoor epoxy resin or
Silicon rubber, and inject in thin wall cavity, repeat A-E steps；
H, product is put into baking oven and carries out solidify afterwards, complete manufacture；
I, cleaning mould is arranged, into next group production.
It is main that this dry solid sleeve insulator internal insulator 1, which uses the epoxy resin with high glass transition temperature,
Insulating materials, there is well mechanically and electrically intensity；Outside full skirt insulating barrier uses high hydrophobic type and high-weatherability asphalt mixtures modified by epoxy resin
Fat or silicon rubber are main material, have excellent weather-proof uvioresistant characteristic, substitute the pottery that original china clay is raw material completely
Porcelain body sleeve pipe；It it also avoid making the situation of the waste of materials of whole insulator using single expensive outdoor resin material, together
When also can the materials'use of External Insulation body have more selections.Using automatic moulding forcing press, particular manufacturing craft, hot pressing are used
Shaping；It has the characteristics of means of production is advanced, and manual intervention is few, and finished product rate is high；The sleeve insulator produced is by umbrella
Together with skirt insulator layer 2 is poured into a mould with interior insulation body 1 and screen layer 3, the product of formation has insulating properties high, and electric property is excellent
It is different, high mechanical strength, the features such as the good weatherability of product, and the sleeve insulator phase formed with single weathe resistance epoxy resin
Than cost can be reduced with highly significant.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not the present invention made any formal
Limitation, every any simple modification, equivalent change and modification for being made to above example of technical spirit according to the present invention,
In the range of still falling within technical solution of the present invention.
